Application filed. February 28,1828. $e1'ia1 n5. 258,115.

This invention relates to an improved construction and control mechanism for flyin machines of the heavier than air type.

roadly considered, among other features,

the invention comprises an aeroplane having an elongated casing provided with longitudinally extending partitions to form with said casing a plurality of superposed air.

containing chambers, in combination with means for entraining air into said chambers through'the cas ng wall for the purpose of directing the currents of a r thus formed in such anianner as both t stabilizethe ma-' chine and control the altitude and propulsion thereof. I

Among the objects ofthe invention are to produce an aeroplane having greater lift ing power, greater carrying power, greater stability, and more evenness in running, and,

in general safer and more eflicient control.

. A particular advantage secured by this in vention is the provision of improved means for safely and efficiently retarding the speed preparatory tom'aking a landing.

Other objectsand advantages may hereinafter appear.

' The invention consists in the various parts, combinations of parts, and the details of construction hereinafter described and at then more particularly pointed out in the claims. i

.liteferringto the accompanying drawings,.

which illustratea preferred embodiment of the. invention,

Figure 1 is a vertical mid-section of the complete machine.

.Figure '2.'s a view partlyin plan -and partly in section, the sectioned ing on line 2+2 ofhigure 1. d

Figure 3 is a vertical'section' on line 33 ofFigurel.

Referring in detail to the drawings, within the elongated main casing 5 is a longitudinally. extending horizontal upper partition 6 and a like-lower partition 7, these partitions 6 and 7 dividing the main chamher intoa. plurality of superposed longitudinal chambers, namely the main central chamber 8, upper auxiliary chamber 9 and lower auxiliary chamber. l0. Theauxiliary' chambers 9 and 10 increase in cross section toward the front end of the machine. With in said main chamber 8 is to be stored freight for shipment and thischamber. also will he equipped to accommodate passengers.

lteferring new to the means for stabilizauxiliary propeller 30, said'propellers being provided on a common driving shaft 31 portion betrolled by contr'ol wires 17. The bottom of the machine is likewise provided with aseries of openings 18 guarded by the valves "19 having control wires 20. Springs 17 oppose control wires-1?, and springs 18 oppose control wires 20.

Referring now to the propellers and means. for operating same, designates the main propeller of usual construction-arid location, which is secured to shaft 26 driven by a motor 27. By this invention are provided a forward auxiliary propeller 29 and a rear driven by a motor 32. Rearpropeller 30 is fixed to shaft 31 and front propeller 29 rotates with said shaft only when clutch 26 is in operation. Clutch-26 isop'erated by control wire 26. A partition separates these two auxiliary propellers;

A'current control air chamber- 37 is provided with upper and lower continuously open apertures 38 and which respectively communicate with the upper auxiliary chamher '9 and the lower auxiliary chamber -.10.

After'being drawn in through said apertures 38 and '39 the air is expelled through the side openings 1 8 (see Figure 2). Through the partition 35 is provided an upper airport 4.0 controlled by a valve 4:1 and a lower air port &2 controlled bya valve 43. 421 and 43 are the controls for "these valves. At the front end of the machine just back of the main propeller are located a circular series of apertures 45. iii-designates the main rudder. v

The machine may be provided with any "desired landing gear, the drawings showing a itront under carriage 60 and rear skid 61.

The'rear skid must support the rear portion of the main casing at a sufiicientheight to 'prevent the relatively large rudder 51 from being injured by contact, with the ground during alighting or starting.

@perationz li?reparatory to beginning a flight, the rear auxiliary propeller 30 is put into operation, the valves ll and 4:8 being maintained closed, and the vaives 19 beneath the lower auxiliary chamber 10 also being closed. Under these circumstances the operation of said propeller 3O entrains air through the upper ports 15 and expels it through the side opening 8 near the front end of the machine justin advance of the main wings at the 'same time directing the air back against these wings. The effect of this operation will be to lighten the machine considerably. When this has been accomplished the main propeller 25 is put into operation,thus driving the machine forwardly and quickly securing a take-off. During the flight the upper valves 16 are closed and the lower valves 19 opened when it is desired to descend quickly to a lower level, and the quick ascension-to a higher level is aided by opening the upper valves 16 and closing the lower valves 1 9, the latter operationbeing always performed when it is desired to descend quickly for landin lVhen it is desired suddenly to check the speed of the machine for alightingor for,

King an air discharge. opening at- 1ts mid any other purpose, the clutch 26 isoperated to put in action the front auxiliary propeller 29'which-eutrains air from auxiliary chambers 9 and 10 through the ports 38 and- 12 and ejects the air from the row of frontports 45.

' I claim:

1. In an aeroplane, an elongated casing having aplurality of superposed longitudinally extending air chambers, the uppermost of said chambers having air openings through the top of the casing, and a propeller adapted to entrain air through said openings, direct it toward the front of the casing and then discharge it in a rearward direction through the'sides of the casing.

2. In an aeroplane, an elongated casing having a plurality of longitudinally extending superposed air chambers, the uppermost of said chambers having apertures through the top wall of the casing, rearw'ardly inclined shutters located on top of said ca'sing adjacent the front edges of said apertures, means for entraining air through said apertures directing it toward the front end of the interior of said casing and then directing it rearwardly and outwardly through apertures in said casing.

3. In an aeroplane an elongated casing, a transverse partition within said casing to form a relatively narrow upper longitudinally extending chamber therein, said partition at its rear end uniting with the top wall ofsaid casing and at its front end being spaced away from said top wall to form an air opening, there being a plurality of openings through the top wall of said casing, and a propeller adapted to entrain air through said top openings, draw it forward over the front end of said partition and then force it outwardly and rearwardly through openings in the casing 4:- In an aeroplane, a casing having a main elongated air chamber, an elongated auxiliary airchamber thereabove, an elongated auxiliary air chamber therebeneath, the front ends of said auxiliary chambers being open and the front end of said main chamber being closed adjacent to the open ends of said auxiliary chambers, said casing havheight at each: side located near the open front ends of said auxil ary chambers and adapted to discharge an outwardly and rearwardly, the upper auxiliary chamber having top air 1nlets and the lower auxili'ary chamber having bottom air inlets, and a propeller to entrain air through the air openings of both of said auxiliary chambers, withdraw itfrom their open front ends and then discharge it from said side openings oi the casing.

5. In an-aeroplane, the combination, with a hull or I casing having apertures in its front end and a main propeller mounted in front of said apertures; of an auxiliary propeller mounted rearwardly of said apertures and means to drive said auxiliary propeller in a direction to force through said openings a current of. air to oppose thc air current created by said main'propeller when it is desired to check the speed of the aeroplane.

In testimony whereof I afiix my signature.
